  1. 1. System for Predictive Life cycle Management of Buildings and Infrastructures

    Författare :Daniel Hallberg; Christer Sjöström; Michel Lacasse; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Management System; service life; performance-over-time; maintenance management;

    Sammanfattning : The Life Cycle Management System (LMS) aims at supporting decision-makers and engineers in their efforts to achieve a more optimised proactive life cycle design and maintenance management strategy. LMS is an open and integrative system, which has to be adapted and developed in order to meet the needs and requirements of users. LÄS MER

  3. 2. Lifetime Performance Assessment of Thermal Systems : Studies on Building, Solar and Disctrict Heating Applications

    Författare :Bojan Stojanovic; Christer Sjöström; Per Jostein Hovde; KTH; []

    Sammanfattning : The main questions today concerning thermal systems are their economical and environmental impacts. These entities are generally, at present, assessed on the basis of operation performances of newly installed/designed systems, during an assumed lifetime period. LÄS MER

  4. 3. Service life estimations in the design of a PCM based night cooling system

    Författare :Göran Hed; Christer Sjöström; Andrew James Miller; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building manufacturing engineering; Byggproduktionsteknik; Building engineering;

    Sammanfattning : The use of Phase Change Material, PCM, to change the thermal inertia of lightweight buildings is investigated in the CRAFT project C-TIDE. It is a joint project with Italian and Swedish partners, representing both industry and research. PCMs are materials where the phase change enthalpy can be used for thermal storage. LÄS MER

  5. 4. Exploring the role of granular activated carbon in drinking water production

    Författare :Malin Ullberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Safe and clean drinking water is recognised as a human right by the United Nations, but water sources world-wide are affected by the widespread use of synthetic chemicals, creating a challenge that drinking water producers must address. Many of these synthetic chemicals, here referred to as organic micropollutants (OMPs), are not well removed by conventional drinking water treatment, and thus additional treatment steps are needed.
